Any inputs or additional thoughts would be appreciated! 

Of course the co-signer should be significantly stronger in ALL areas as compared to the applicant...usually this is a parent or relative, and they should be well established, with ownership of real estate for years; long and stable employment; no, or very distant, criminal and traffic court records; well funded SAVINGS/IRA's or stock market accounts.

I successfully run 1 STR and have a 2nd that an inherited PM handles.I have Vrbo and Airbnb they will sync with each other with no external software.I set pricing easily by using the built in tools that Vrbo provides.Automated messages are built into both platforms.Vrbo keeps my calendar slammed, but I take direct bookings as needed, simple to do.I have no additional 3rd party fees to very sucessfuly run and manage my property needing only a a few minutes per week.

As far as permits and renovations and ADU additions?

As an individual with an FHA loanI appreciate any additional guidance you all have for me.Thanks! 

IRA annual max 7k vs 401k $69k.  

@Kevin Sobilo, do you happen to have additional information regarding the changes to the rules regarding how basements are appraised?  

Thorough vetting is absolutely essential in private lending to mitigate risks and protect your investment.Here are a few additional tips to enhance your due diligence process-Assess Their Exit Strategy: Whether it’s a flip, rental refi, or sale, make sure their exit strategy is realistic and aligns with market conditions.

They completed the review of the voucher on December 3rd AND REFUSED TO COVER THE TENANT'S RENT FOR NOVEMBER because they didn't have LMHA permission to move in.We had a home pass inspection on December 20th and still haven't received permission for the tenant to move in (January 3rd)...the tenant just had to pay for an additional month's rent at their old home and we are out another month without our rental occupied, incurring carrying costs, and risking vandalism.

That said, if you can comfortably handle the additional down payment and monthly payment consequences of a higher purchase price (and the lenders agree), and you have a few different good options with the property then it could be a wise investment.By a few good options . . . you want to have some exit strategy other than STR that will work in case the something happens to make STR uncouth in your area.
